| Abstract |
Background and Objectives
Honey has various biological and pharmacological activities and has been used as treatment against various inflammatory diseases. The aim of this study was to compare the anti-inflammatory characteristics of manuka, kanuka, and black locust honey.
Materials and Method
Peripheral blood mononuclear cells (PBMCs) from healthy human volunteers were isolated and then stimulated with lipopolysaccharide (LPS) with or without pre-treatment of various concentrations of honey for 72 hours. The cytotoxic effects of honeys were measured using an aqueous cell proliferation kit, and the supernatants were analyzed for interleukin-5 (IL-5), IL-10, interferon-γ (INF-γ), and tumor necrosis factor-α (TNF-α) using an enzyme-linked immunosorbent assay.
Results
Samples of 1% manuka and kanuka honey were found to have cytotoxic effects on PBMCs. Honey itself enhanced the production of IL-10 and TNF-α production. Manuka and kanuka honeys suppressed LPS-induced IL-10 and INF-γ production, while black locust honey only suppressed IL-10 production from PBMCs.
Conclusion
Honeys had immunomodulatory properties of both immunostimulatory and immunosuppressive effects on PBMCs. Different honeys might have different immune modulatory functions due to their different components. |
